Here there were Dragons.

The Great Invasion

Ten years ago ships flying strange colors led my fearsome dragonborn landed on the sword coast and took Waterdeep. They claimed to be from Alteir, a land far across the Trackless Sea. Also, they claimed to be descendants of the Dragons of Faerun and had come to reclaim their homeland. They began taking cities and forcing the people to swear oaths of fealty to the crown of Alteir, Isa Pliankif, may she live forever. Perhaps worse than the oaths were the collars – strange leash-like devices that could seemingly enslave those sensitive to Arcane or Primal magic. The Alteirans would take new territory and enslave local magic users, adding to their own forces.

The war lasted for 7 years, devastating the western portion of Faerun and would not end until a coalition of nations and an alliance with the Drow of the Underdark took up arms together and drove the Alteirans back across the Trackless sea. It is not known if they are truly beaten and many fear the return of the “true” masters of Faerun.
